Eichinger Receives $406,000 USDA Grant To Study Animal Confinement Emissions

William Eichinger, professor of civil and environmental engineering in the University of Iowa College of Engineering, faculty research engineer at IIHR-Hydroscience & Engineering and researcher in the Center for Global & Regional Environmental Research, has received a three-year, $406,000 U.S. Department of Agriculture grant to develop a new approach to rid animal husbandry facilities of methane and other emissions.

Formally titled, "New Approach to Emissions from Animal Husbandry Facilities," the project is designed to determine the way in which a variety of chemicals are released from animal facilities, then propose novel approaches to combat the problem. According to Eichinger, the problem of emissions that has long plagued animal facilities can be alleviated through the application of modern technology.

"The lidar (laser radar) devices at IIHR are capable of mapping the concentrations of particulates and some chemicals in the atmosphere," he says. "Mapping of particulates can be done fast enough to make 'movies' of the emissions from the facilities. These movies have shown that the ways in which effluents from the facilities are released is quite different from the conventional assumptions. This has implications for the amount of effluent released and the way in which mitigation is done. Another benefit of the research is that improved estimates of downwind concentrations can be made."

In October 2005, Eichinger received a two-year, $322,000 National Science Foundation (NSF) grant to investigate the chemical composition of smog in Mexico City. The project will use laser radar to measure the chemical and physical changes in pollutants emanating from Mexico City, currently the world's second largest metropolitan area and, eventually, help mitigate the effects of atmospheric emissions.

Eichinger, who earned his doctorate in hydrologic science from the University of California-Davis in 1995 and joined the UI faculty in 1997, has specialized knowledge in the fields of hydrology and fluid mechanics in the environment, atmospheric pollution control and remediation, optical remote sensing, lidar and nuclear physics.
